Selected aspects of the effect of mechanical treatment on surface roughness and adhesive joint strength of steel sheets

The following paper analyses selected problems regarding the impact of technological parameters and the type of adherend material on the strength of adhesive-bonded steel sheet joints. The subject of the test was a single-lap adhesive joint of S235JR steel sheet. Joints were formed on two types of substrates: with or without corrosion products on the surface. The surface of steel sheet adherends was pre-treated with three cleaning solutions: acetone, Wiko industrial degreasing agent and Cortanin F anti-corrosion agent, depending on the state of the surface. Adhesive joints were formed with Epidian 53/ET/100:15 epoxy adhesive. The formed joints were subjected to one of three ageing variants: 14 days, two months and 3 months, which were followed by destructive testing to determine the shear strength of joints. The analysis of results obtained in the tests indicates that the strength performance of adhesive joints of corrosion-free adherends was characterised by higher values than in corroded steel sheets, regardless of ageing time.

The paper investigates the compression strength of samples of regenerative polymer mass RM 101 Resimetal Metal Repair Pasta manufactured by Rendor. The effect of weather conditions on selected mechanical properties of the tested mass is examined. The samples are subjected to seasoning at room temperature, in an environmental chamber, and in a thermal shock chamber. The samples for strength testing are made according to the adopted method. It has been observed that the samples seasoned at room temperature have the lowest strength, while the highest strength is exhibited by the samples subjected to seasoning in an environmental chamber at a temperature of 70°C and humidity of 95%. In addition, the paper compares the strength properties of regenerative polymer masses manufactured by Chester Molecular, Belzona, and Unirep, as well as of the widely used epoxy compound Epidian 57 mixed with the Z-1 curing agent with those of the Rendor mass. The properties of the above masses are obtained from the available literature.

“…Adhesive joints control process comprises a number of operations during which factors regarding joint production and finished joints are scrutinized [1][2][3][4][5][6]. Due to the fact that adhesive bonding is regarded as a special joining process it requires specific approach, accounting for the necessity to apply a variety of different test methods to control the finished joint, as well as joint formation processes [7][8][9][10][11].…”

This article presents selected criteria for the quality assessment of single-lap adhesive joints formed on 0.66±0.04 thick hot dip zinc coated sheets with the hot dip zinc coating thickness equal to 18 µm. Three types of epoxy adhesives and three variants of the mass of adhesives were tested (1 g, 2 g and 3 g). The work intended to assess the capacity of the visual method with regard to evaluating joint quality, allowing for the presence and the size of spew fillet, joint dimensions and the effect of spew fillet on adhesive joint strength. The strength of analysed adhesive joints was determined in destructive tests.
